Many drivers can't see themselves at the wheel of an electric vehicle in the near future, and the brakes on uptake can vary from country to country. While price is the most discouraging factor in France, for people in Germany and China, it's the lack of charging stations that's particularly offputting.

Travel routes

Between Nice and Menton the mountains plunge sharply down to the sea. Running along these heights are three famous routes: the Grande Corniche, the Moyenne Corniche and the Basse Corniche. The first affords the most stunning views, climbing to 1,476ft/450m. The second offers beautiful vistas along the shore; while the third provides access to the coastal resorts.
